Arguments

comparator  (symbol, function, lambda) function used for the boolean comparison; must return NIL resp. non-NIL
lst  (list) any list of items

Return

list of all items, starting with the first item which does not match the comparator function; if all list item match the comparator, NIL is returned

Example

(vl-member-if-not '(lambda (x) (< x 5)) '(1 2 3 4 5 6 7 8 9 10))
returns (5 6 7 8 9 10)

Remarks

validation of each list item stops at the first item, which does not match the comparator function (that is, the comparator function returns NIL), and returns the remainder of the list, from that item
